do i need to run in my 305 75 16 tires on 8 in wheels? i dont do any hauling of anything very heavy and no off roading

 

run the pressure listed on the tire place card on the door jam

most people think because they have bigger tires they need more pressure witch is wrong you only need more air in the tire to reach that pressure

 

...OR the pressure indicated on the sidewall of the tire!

 

Read the script on the sidewall,everything you need too know.Just a thought..

 

What color is your truck?

 

The pressure on the sidewall is the MAX the tire should be inflated to. Read what's on the sticker on the door or in the door jamb. Should be either 35 or 50 psi. (My truck says 50) if yours is 50 your tires should be load range E and you should have high pressure valve stems

 

Nyuck...Nyuck...

 

i dont know if you are joking or not but the sidewall only has a max psi witch is to much usually on a lt tire

 

For reference,

I have 285/75/16 load E tires. My truck is a 1/2 ton (1500) 4wd. I hual 2500-3000 lbs. in the bed at times; maximum factory capacity is 1500ish lbs. and I also have a plow hanging on the front (400 lbs.). I run 45 psi in all tires.

Normally if you dont haul or have excess weight (plow, etc.) the standard 35 psi should be fine.

 

the sticker on the door jam is ONLY for the type and size tire....described on door jamb. In other words, OEM tires. Since OP is going to a different size/type of tire, it is NOT necessarily appropriate for his new tires!

And my tires list Min and Max tire pressure range...on all of my vehicles.
